Gravity and centrifugal forces

If you jumped on an orbital/halo.. Would you carry on flying through the air indefinately or does the centrifugal force push you towards the ground even though you are not in any physical contact with the centrifugalised object??

On a planet we're attracted back towards the ground by gravity.. theres no gravity on a orbital/halo

Since you were in contact with the spinning object when you jumped you still will have a tangential velocity in addition to the upwards velocity of your jump. This puts you in a straight line trajectory that intersects the inside of the Halo. Since the halo continues to turn while you are in the air, you will intersect the inside surface at almost exactly the same physical spot as you jumped from. From your perspective, it will seem like you jumped straight up and came straight back down.
